Question

The solute cannot be separated from solution by filtration

Answer 1

Filtration is the process of separation which can separate a substance from its medium considering the size of the particle to be separated should be large enough. Since the particle of solute within a solvent is very small they tends to pass through the filter paper along with solvent and do not get separated.

Example : Sugar as solute in the solution of water cannot be separated through distillation because the size of the sugar particles is very small.
